Engineers in industries such as Energy, Chemical Process, and Life Sciences will benefit from the addition of passive scalars for the Lagrangian and DEM models. Passive scalars allow particles to carry additional information such as the thickness of a coating being sprayed onto the particles (via an Eulerian passive scalar), or the water content of particles being dried. Passive scalars enable you to determine the effectiveness of mixing processes where previously it would have been impossible to distinguish particles from each other, which in terms of the physics being modeled were otherwise identical.
